Danny Kedem quit as Weiner’s campaign point man following a disastrous week on the trail, the embattled mayoral candidate confirmed this morning.

“Danny has left the campaign. He did a remarkable job,” Weiner said

“We have an excellent staff. More people have come on, frankly. We’ve gotten more volunteers and more people coming over to help the campaign in the last several days than anytime since the campaign started.”

With Kedem out of the already shrunken campaign staff, the longshot City Hall bid appeared to be floundering.

Weiner stood firm despite his travails yesterday, spending much of the day in his apartment shooting a campaign ad.

“I am running for mayor of the city of New York, and I plan on winning,” Weiner told The Post in the afternoon — though it was unclear if he knew at the time that his quarter-back was sacking himself in the wake of unabating blow-back from his extra-marital shenanigans last summer with sext kitten Sydney Leathers.

Even though Leathers said she’s “disgusted” by Weiner, pals of the pretty brunette said she doesn’t mind attention from financially well-endowed men.

Leathers was a gold-digging social climber who trolled Internet “sugar daddy” sites for wealthy men — and was not above taking a few Benjamins just for “talking,” according to her online chats and profiles, as well as school pals.

She went for Weiner, but her friends say cash was her real turn-on.

“She used sugardaddy.com to meet men,” said a 27-year-old former girlfriend from Chicago who requested anonymity. “She met a few guys on that site when she was visiting me. She wants the lifestyle without working for it.”

Leathers called herself a “22-year-old SugarBaby,” according to her profile on the SugarDaddyForMe dating Web site.

Last summer, even as she was sexting the married and already scandal-scarred ex-congressman, Leathers used her friend’s condo as her home base for dating wealthy Chicago men, according to her ex-pal, who said Leathers “was actively seeking men out to pay for her.”

Then she’d boast about her conquests in texts, said the ex-pal, backing her story with a copy.

“Are you at your place?” Leathers, using the name “Sydney Elaine,” texted in August 2012 to her pal, who answered, “Yeah” and “Why.”

“I’m on my way back now,” Leathers said.

When the pal asked “How was it,” Leather gloated, “I got $200 just for talking to him lol. He wants to see me Monday & give me more cash :)”

Leathers’ texts and tweets also revealed that, during the period when she was exchanging nudie pics with Weiner, she was bragging smoking pot and taking Prozac, sleeping pills and Xanax.

“On Facebook, she posted something a few months ago. She said she had some big secret that could ruin someone’s life,” another high-school classmate, Ryan Hindliter, 23, told The Post. “I guess she might have been talking about Weiner. She always loved attention . . . She was always posting on Facebook and complimenting her own photos.

“I think this was all done to get fame and fortune, and the way she could do this was by throwing him under the bus before the election.”

“She got exactly what she wanted — 15 minutes of fame . . . like this is her big shot,” he added.
